ABSTRACT Sources of water use by 10 alluvial trees in various hydrogeological and ecological situations at the Pfyn forest (Wallis canton, Switzerland) were assessed analysing 18 O 2 H isotopes precipitation, soil different depths, surface water, groundwater xylem sap. The line a δ versus diagram shows evidence kinetic fractionation related to evaporation. tree is close trend; however, an additional enrichment may occur could be xylem–phloem communication under stress. At sites where table...

Due to the current analytical processes that are not able measure all pharmaceutical molecules and high costs consumption of time sample analyze PhACs, models calculate Predicted Environmental Concentrations (PECs) have been developed. However a comparison between MECs PECs, taking into account methods calculations peculiarly parameters included in calculation (consumption data, pharmacokinetic parameters, elimination rate STPs environment), is necessary assess validity PECs. MEC variations...

Steel-making slag is largely used today in road construction and other applications, but significant volumes are landfilled cannot be recycled for excessive contents hazardous metals, such as chromium or vanadium. The long-term behaviour of this material still little known, the characterisation large volume dumps remains an environmental challenge. In study various analytical techniques to characterise Electric Arc Furnace (EAF) several decades exposed chemical weathering erosion. Coupling...

The Kerguelen Islands, located in the southern part of Indian Ocean, are very isolated geographically. microbial diversity and communities present on island, especially associated to geothermal springs, have never been analyzed with high-throughput sequencing methods. In this article, we performed first metagenomics analysis microorganisms hot springs. From four assembled metagenomes recovered 42 metagenome-assembled genomes, mostly new putative taxa based phylogenomic analyses overall...

Abstract Peatlands provide a large panel of socio‐ecosystemic services such as biodiversity, water and carbon storage amenities. Hydrological geochemical interactions between peats their surroundings are expected to be favoured in mountainous areas, which nowadays increasingly sensitive climate changes. In order an integrated scheme potential interactions, this study evaluates spatio‐temporal patterns environmental tracers ( 87 Sr/ 86 Sr, δ 18 O/δ 2 H, elemental ratios) during high‐ low‐flow...
